Application filed October 2, 1918.

To allw'hom it may concern Beitknown that I, ALBERT L. ARENBERG, a-citizen of the UnitedStates, residing at Chicago, in thecountyof Cook and State of Illinois, have invented a certain new and useful l-mprovement in Shade-Holders, of which the following is a specification.

My invention relates to shade holders, for example such as are-used for: electric lighting, and the object of the invention is to provide simple, quickacting and secure means whereby the shade may be attached to and detached from the holder.

1 accomplish my object by the mechanism illustrated in the accompanying drawings in which Figure 1 is a sectional elevation of my device on the line 1-1, Fig. 5, showing it under actual working conditions.

Fig. 2 is a perspective view of the catch forming one of the important features in my invention.

Fig. 3 is a plan view thereof, and

Fig. 4: an elevation.

Fig. 5 is a top plan view showing the relative location of the lugs and catch.

Similar numerals refer to similar parts throughout the several views.

It will be understood that the shade holder, shade, lamp and globe may assume various forms. but in the form selected to illustrate the invention the shade holder 1 has a socket 2 for receiving the base of an electric lamp 3. The lamp is surrounded by a globe 4L which rests upon the flange 5 of the shade 6. Said flange is annular and projects outward as is the case, in some form or other, of most commercial shades.

Inside of the flange 7 of the shade holder are lugs 8 for supporting the flange 5. These lugs are here shown in the form of inward projecting pins arranged 120 apart. At a point 120 from each of themthat is on the opposite side of the shade holderis a catch 10 hinged to cars 11 rigidly secured to the shade holder by means of a screw 12 or otherwise. It will be understood of course that these cars may be of cast metal integral with the remainder of the shade holder. .The catch is pivoted upon the horizontal hinge pin 14, and the parts are so arranged that when the catch is down in acting position its lip 15 will pass to the inside of the holder, extend under the flange 5, and support the shade as best shown in Fig. 1. The catch is locked in acting posi- Specificacionof Letters Patent.

tionwby a latch 17 pivoted on apin l8 and adapted to drop into the socket 19 behind the catch. The latch extends beyond socket 19 toafford ahandle by which it may be manipulated, and is held to its workby a keeper 20. A set screw 21 screws into the catch above latch 17 in such manner that whenscrewed home as shown in Fig. 1 it will prevent the latch from rising. Thus the parts will be securely locked together andthe shadewill be locked in the holder.

This avoids any danger of throwing the latch back and releasing the catch when the fixture is being dusted or manipulated.

In operation, when it is desired to install the shade, the flange 5 is first placed upon the lugs 8. This supports one side of the shade. The catch is then thrown back as shown in perspective in Fig. 2. The adjacent proportion of the shade is thereupon elevated until the shade reaches the position shown in Fig. 1. The attendant then permits the catch to drop to acting position, after which he lowers latch 17, permitting it to drop into the socket 19 behind the catch. As a matter of security he then screws home the set screw 21 which prevents the latch from being accidentally lifted.

The advantage of this construction lies in the simplicity and ease in which the shade may be placed and removed and the security with which the shade is held. Manipulation is required at only one point and that'is at the catch-and the catch itself is rugged and easily manipulated with one hand. The set screw is a mere safety device and does not support any of the weight of the shade. Consequently, there is no danger that the shade will damage any of the threads or bend the screw which is apt to be the case in fixtures in which the shade is supported by a screw. speaking, there is nothing to wear out, and the attendant can tell at a glance whether the shade is securely installeda fact which is not readily determined where a set screw directly engages the shade.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent, is

1. A shade holder having a catch adapted to swing toward and from the shade for engaging and disengaging it, and a bar pivoted to the shade holder and adapted to drop behind the catch for holding it in acting position.

Practically v 2. A shade holder for supporting an annularly flanged shade, said holder having lugs at one side for engaging the flange of the shade at points remote from each other, and a catch symmetrically located With respect to said lugs for cooperating with them to support the shade, said catch being hinged to the outside of the shade holder and passing to the inside 01 it to engage the flange of the shade, and a latch adapted to drop behind the catch for looking it in act ing position.

3. A shade holder for supporting an annularly, flanged shade, said holder having lugs at one side for engaging the flange of the shade, and a catch symmetrically located with respect to said lugs, said catch being suspended between ears on the holder and Copies of this patent may be obtained for being swingable in a vertical plane, a pivoted latch adapted to swing behind said catch for holding it in acting position, and a keeper for holding said latch to its Work.

t. A shade holder having means at one side for engaging the shade, and at the opposite side a catch pivoted to the holder and swingable in a vertical plane to engage and disengage the shade, a latch pivoted to the holder and adapted to drop behind the catch for holding it in acting position, a keeper for holding the latch to its Work, and means for preventing the rise of the latch.

In Witness whereof, I have hereunto subscribed my name.

ALBERT L. A'RENBERG.
